//                 --- ZScript built-in functions and variables ---
//===================================================================================
/*
* 	These functions are all INTERNAL to ZQuest. They require no header
* 	or other import directives to work, and are all direct representations
* 	of ZASM instructions. 
*
* 	These functions and commands are the BASIC BUILDING BLOCKS of ZScript:
* 	While they require no other functions to work, ALL other functions 
* 	in headers (such as std.zh) RELY, and OPERATE using these functions.
*
*	Thus, it is essential to know what each of these does, how they work,
* 	and how to use them. 
*
* 	For other included functions, that are not internal (i.e. external functions)
* 	please read the documentation specific to  each header. These are individual 
* 	files (e.g. std.txt), however if you wish to view all the pre-packaged ZScript
* 	functions, and commands, you may view the EXTENDED DOCUMENTATION, as
* 	those documentation files contain all of the 'Essential ZScript' that
* 	you will want to use.
*
* 	Where possible, the ZASM instruction used by the functions, and the
* 	commands detailed herein are listed inline with the entry for the related
* 	function / command. Full (public) ZASM documentation is, sadly incomplete.
*
* 	Note: Functions and variables other than global functions are properties
* 	of **objects**. Objects are divided into TYPED POINTER CLASSes, and the 
* 	the syntax for using them is:
*
* 	[object name]->[property]
*
* 	where "[object name]" is the object's name (e.g. Link, Game, Screen)/
* 	and "[property]" is the function. 
*	
* 	Example:
* 	void GetCurDMap() is a Game property, and is called as:
*
* 	Game->GetCurDMap();
*
* 	"Link", "Screen" and "Game" are always available and don't need to be 
* 	instantiated, while you must initialise other classes, such as ffc, item,
* 	and npc.
*
* 	ZScript functions are of the types: int, float, bool, and void. Of these,
* 	only void does not return a value. (The void type is normally used to run
* 	a series of instructions, or to set values). The other types retrun values
* 	appropriate to their type.
*
* 	Note: In the following, "int" indicates that a parameter is truncated by a 
* 	function to an integer, or that the return value will always be an integer 
* 	however, ZScript itself makes no distinction between int and float types.

//////////////////
/// ZASM Flags ///
//////////////////

ZASM uses a series of special flags, to determine how it should follow logical instructions,
including the following:

SCRIPT FLAGS
TRUEFLAG : A condition in the script, is true
MOREFLAG : Must be set manually with ZASM. 
FALSEFLAG : Must be set namually with ZASM. 
LESSFLAG : Must be set manually with ZASM.

Instructions
SETTRUE : Set the Script Flag TRUEFLAG.
	SETTRUE Sets a true condition for the Assembler, if a COMPARERV and COMPARER validate.
	This is used when making statements in ZScript. 
SETFALSE: Set the Script Flag FALSEFLAG: ZScript does not do this. 
SETMORE : Set the Script FLag MOREFLAG: ZScript does not do this. 
SETLESS : Set the Script Flag LESSFLAG: ZScript does not do this. 

These flags are used in evaluation instructions, to determine if an instruction should run.

Examples of these are as follows:

GOTOTRUE: Executes the GOTO instruction only if the Script Flag TRUEFLAG is enabled.
GOTOFALSE: Executes the GOTO instruction only if the Script Flag FALSEFLAG is enabled.
GOTOMORE: Executes the GOTO instruction only if the Script Flag MOREFLAG is enabled.
GOTOLESS: Executes the GOTO instruction only if the Script Flag LESSFLAG is enabled.

In contrast, GOTO/GOTOR ignore all flags, and conditions.

ZScript always compiles down to GOTO, GOTOR, and GOTOTRUE instructions. 
The other FLAG-typed GOTO instruction types are valid only in ZASM, and serve no useful purpose.
GOTOLESS, GOTOMORE, and GOTOFALSE are effectively deprecated. 

//================================================== =====
//--- Instruction Processing Order and General Timing ---
================================================== =======

1. 	Instructions in Global script Init (if starting a new game)
2. 	Instructions in Global Script OnContinue (is resuming a game)
3. 	Instructions from FFCs that run on screen init, excluding draw instructions.
		Note: Instructions are handled on a per-ffc basis, in ID order; so a script on ffc ID 1 runs,
		then a script on ffc ID 2, up to ffc ID 32. If an ffc has no script, it is skipped.
4. 	Instructions immediately inside the run() function of a global active script, if the game has just loaded.
5. 	Instructions in the global active script's infinite loop prior to Waitdraw,
6. 	Instructions from an ffc script positioned after (an illegal)
	Waitdraw() instruction in that script from the previous frame.
		Note: Requires being on at least the second frame of a game session.
7. 	Screen bitmap drawing.
8. 	Enqueued Script Drawing from the global active script, (and from ffcs on the previous frame).
9. 	Drawing Instructions in the global active script prior to Waitdraw().
10. 	Instructions in an ffc script, excluding draw commands.
		Note: Instructions are handled on a per-ffc basis, in ID order; so a script on ffc ID 1 runs,
		then a script on ffc ID 2, up to ffc ID 32. If an ffc has no script, it is skipped.
11. 	Screen Scrolling (2.50.2, or later)
12. 	Waitdraw() in a global active script.
13. 	Engine writing to Link->Dir and Link->Tile.
14. 	FFCs enqueue draws for the next frame.
		Note: Instructions are handled on a per-ffc basis, in ID order; so a script on ffc ID 1 runs,
		then a script on ffc ID 2, up to ffc ID 32. If an ffc has no script, it is skipped.
15. 	Instructions from item action scripts.
16. 	Instructions from item collect scripts.
17. 	Instructions in the global active script, called after Waitdraw()
17(b). 	Screen Scrolling ( 2.50.0, and 2.50.1 )]
18. 	Instructions in an OnExit script, if the game is exiting.
19. 	Return to (3).


//=================
//--- Pointers ---
//=================

Global array pointers start at 4096 (when traced). These are added in escalating value, but in the reverse-order
of declaration. e.g. The last declared array will be ID 4096.

////////////////////////
/// Operator Symbols ///
////////////////////////

ZScript supports value input as decimal, hexidecimal, and binary. 

To input hexidecimal values, preface them with '0x'. Thus, '0x0F' for '16'.
To input binary balues, end them with a lowercase 'b'. Thus, '11b' for '3'. 

Name		Sign	ZASM (R)	ZASM (V)	Definition
PLUS		+ 	ADDR<><>	ADDV<><>	Adds a value a + b, a + 3
MINUS		-  	SUBR<><>	SUBV<><>	Subtracts a value a - b, a - 2
INCREMENT	++  					Increments a value by '1'
DECREMENT	--  					Decreases a value by '1'
MULTIPLY	*  	MULTR<><>	MULTV<><>	Multiplies values a * b
DIVIDE		/  	DIVR<><>	DIVV<><>	Divides values a / b
MODULUS		%  					Returns the remainder of integer division of 4 % 2
NOT		!  	NOT<>				Inverse logic boolean operator. 
							if ( !var1 == 0 ) returns true if var1 is zero, 
							and false if var1 is non-zero
EQUALS		=  	SETR<><>	SETV<><>	Sets a value to another value a = 4
EXACTLY EQUALS	==  					Compares value a == b and returns if they match.
NOT EQUALS	!=  					Compares values a != b and returns if they do not match,
LESSTHAN	<  					Comapres a < b and returns if a is less then b.
MORETHAN	>  					Compares a > b and returns if a is more than b.
LOGICAL OR	||  					Boolean logic, Or.
LOGICAL AND	&&  					Boolean Logic And.

SET ADDRESS ARG		SETA1<><>
			SETA2<><>
GET ADDRESS ARG		GETA1<><>

/////////////////////////
/// General Functions ///

void Waitdraw();		ZASM Instruction:
				WAITDRAW
/**
* Halts execution of the script until ZC's internal code has been run (movement,
* collision detection, etc.), but before the screen is drawn. This can only
* be used in the active global script.
* Waitdraw() may only be called from the global active script; not from FFC scripts.
* The sequence of ZC actions is as follows:

* FFCs (in numerical sequence, from FFC 01, to FFC 32)
* Enemies
* EWeapons
* Link
* LWeapons
* Hookshot
* Collision Checking
* Store Link->Input / Link->Press
* Waitdraw()
* Drawing
* Rendering of the Screen
* Screen Scrolling
* Drawing from FFCs
*
* Note: Drawing from FFCs technically occurs with other Drawing, but as it is issued after Waitdraw(),  
* it is offset (a frame late) and renders after screen scrolling, and after any other drawing in the same 
* frame as draw instructions from ffcs are called. To ensure that drawing done by ffcs is in sync with 
* other drawing, it is imperative to call it from your global script, using the ffc to trigger global 
* conditions that cause global drawing instructions that are called before Waitdraw() in your global 
* active script to evaluate true. 
*
* Anything placed after Waitdraw() will not present graphical effects until the next frame. 
* It is possible { ! CHECK } to read/store Link->Tile, Link->Dir and other variables *after* Waitdraw()
* in one frame, and then use these values to modify other pointer members so that they are drawn correctly
* at the next execution of Waitdraw().
*
*
*/ Example Use:

	Waitdraw();
	
//! Submit bug report that Link->Dir and Link->Tile are incorrect before Waitdraw. 
	
*//////////////////////////////
* Waitdraw() in ffc scripts ///
* --------------------------///
* Althouth technically illegal, it is possible to call Waitdraw() in an *ffc script*. Doing this has the 
* following effects, and/or consequences:
* 
* 1. The Compiler will report an error, and print the error to Allegro log:
*	'Warning: Waitdraw() may only be used in global scripts.'
* 2. Any instruction sint he ffc script that are called before the Waitdraw() instruction in the ffc script 
*    will run this frame, after Waitdraw() in your global active script.
* 3. Any instructions called *after* Waitdraw() in the ffc script, will run BEFORE BOTH Waitdraw() in your
*    global active script, and BEFORE any other instructions in your global active script's infinite loop. 
*
* This behaviour may change in future versions of ZC, and using Waitdraw() in ffc scripts is not advised. 

*///////////////////////////////
* Waitdraw() in item scripts ///
* ---------------------------///
* Althouth technically illegal, it is possible to call Waitdraw() in an item sctipt. Doing this has the 
* following effects, and/or consequences:
* 
* 1. The Compiler will report an error, and print the error to Allegro log:
*	'Warning: Waitdraw() may only be used in global scripts.'
* 2.
*
* This behaviour may change in future versions of ZC, and using Waitdraw() in item scripts is not advised. 

/************************************************************************************************************/

void Waitframe();		ZASM Instruction:
				WAITFRAME
/**
* Temporarily halts execution of the current script. This function returns at
* the beginning of the next frame of gameplay.
* Slots 1, 3 and 4 Global scripts and item scripts only execute for one frame,
* so in those scripts Waitframe() is essentially Quit().
* It is safe to call Waitframe in the active global script.
* A Waitframe is required in all infinite loops (e.g. while(true) ) so that ZC may 
* pause to break in order to advance to the next frame, then resume the loop from the start.
*
*/ Example Use:

	Waitframe();
	
*///////////////////////////////
* Waitdraw() in item scripts ///
* ---------------------------///
* Althouth technically legal, it is invalid to call Waitframe() in an item sctipt. Doing this has the 
* following effects, and/or consequences:
* 
* 1. The script will prematurely exit. 
*
* Calling Waitframe() in an item script is effectively identical to calling Quit(), however this behaviour 
* may change in future versions of ZC, and using Waitframe() in item scripts is not advised. 

/************************************************************************************************************/

void Quit();			ZASM Instruction:
				QUIT
/**
* Terminates execution of the current script. Does not return.

/**
* Copies the tile specified by scrtile onto the tile space
* specified by desttile. The valid tile value range is 0 to 65519.
* This change is temporary within the quest file
* and not be retained when saving the game.
*
*/ Example Use:

	CopyTile(312,11614);
	Copies tile 312, to tile 11614. Tiles 312, and 11614 will be identical.

/** TIP **
* CopyTile may be used to change Link's tile, by copying a tile onto whatever tile ZC is
* using as a source for Link->Tile
* Thus, although you cannot write directly to Link->Tile, you can write to the actual tile 
* that is being used for this Link attribute, and you can do this for any other game graphic
* that you need to change. 
*
* When doing this, it is important to read Link->Dir or Link->Flip, *after* Waitdraw() and 
* perform the CopyTile() operation immediately thereafter.

		    Drawing colour 0 to a layer of a bitmap render target erases a section of that,

//////////////////////////////////////////////
/// System Limitations, Minimums, Maximums ///
//////////////////////////////////////////////

     Maximum numeric literal: 214747.9999

Ints, Floats, Arrays

	Maximum float: -214747.9999 to 214747.9999
	Maximum int -214747 to 214747
	Maximum array size (number of indices): 214747

	* This further includes arrays with a type of npc, leweapon, eweapon, item, and itemdata. 
	Maximum value in an array index: Same as float, or int; based on type declaration.
	Maximum size of string index: 214747
	Maximum string length: 214747
	Maximum simultaneous arrays in operation: 4095

Counters, Tiles, Combos, Strings

	Maximum Tiles: 65519
	Maximum Combos: 65279
	Maximum Counter Value: 0 to 32767
	Maximum strings in string editor: ( 65519 )

	Largest tile ID (ZQ Editors): 32767 ? 

	The largest value that can be referenced in the ZQ item, enemy, and other editors.

                --> I seem to remember a problem calling high values.
		
Pointers and Objects

	Maximum number of item pointers (on-screen items) at any one time: 255
	Maximum number of lweapon pointers (on-screen lweapons) at any one time: 255
	Maximum number of eweapon pointers (on-screen eweapons) at any one time: 255
	Maximum number of npc pointers (on-screen NPCs) at any one time: 255
	Maximum number of ffc (on-screen FFCs) pointers at any one time: 32
	Array Pointers (maximum number of arrays in operation): 4095

	Maximum total (cumulative) number of 'object' pointers at any one time: 1020 
		* 255 each, npc, lweapon, eweapon, item + 32 (ffcs)

	--> ZC separates pointers by class. All pointers are stored in vectors, with pointer IDs ranging from 1 to 255. 

	Maximum Z Height of a Screen Object (npc, weapon, item) or Link: 32767. Values above this wrap to -32767, which is reset to 0 every frame. 

Compiler

	Maximum constants (any scope): Unlimited. (Constants are converted to their true value at compilation, and are not preserved by name.)
	Maximum global variables: 255*
	Maximum global functions: 4,294,967,295 (2^32-1). 
		Note that this is limited by the filesystem, as each function requires its ASCII size in bytes, 
		and is stored in the quest file. Many filesystems have a file size limit, that restricts it. 
		At the smallest function size, max functions would use ~40GB of space. 
		It is further restricted by the maximum buffer size at between 18MB and 22MB.

Script Drawing

	Maximum number of drawing commands per frame: 1000
	Maximum distance (x,y) for drawing, including off-screen areas (and bitmaps): -214747.9999 to 214747.9999 (X and Y)
	Maximum Z Height for 3D Drawing: 214747.9999

		--> Negative Z Height is effectively '0'. 

Stack Operation

	Maximum number of concurrent stacks: ? 
		--> Essentially, the maximum number of concurrent scripts; except that item scripts share one stack.

	Maximum variables in operation at any given time: 255* (gd1-gd255)
	Maximum variables per script: 255*
	Maximum function calls per script ( 127* )
	*Note: 255 variables will compile, but fail to run. A safe maximum is closer to 245, to allow instructions and function calls on the stack
	*Note: Both variables, and function calls share registers (global variables are gd registers), and thus cumulatively count against their combined caps (within a register type). See: ZASM_Registers
                --> How are these tabulated at compilation, and is there a strict ratio ( function call:variable ) ?
                --> Script-scope variables use gd registers. Thus, you need to retain free registers for scripts to run. 

	Maximum script buffer size: ~18MB, including code imported with the 'import' directive. 
                --> Maximum line count is also limited, but it is restricted by being a signed int. 
                --> Thus, max line-count is somewhere around 2,147,483,647 lines, however, 
                    this is still restricted by the 18MB buffer size.  

	Maximum number of instructions: 2^32-1 * Max Scripts
	Maximum instructions per script: 4,294,967,295 (2^31 - 1)
	Maximum instructions per frame: Effectively unlimited, save by instructions per script. 

	Maximum number of scripts ?
	Max ffc scripts at compilation ?
	Max Item scripts at compilation ?
	Max global scripts at compilation ? 
                --> I know this is unlikely to ever be reached.

	Maximum function calls per script: Limited by maximum instructions, and available gd registers.
	Maximum local functions per script: ? Effectively unlimited, and tied to maximum functions (see above). 

Maximum Values (Binary, Hex) for Use as Flags

	The largest literal that you can use as a flag, binary, is: 110100011010111101 
		( dec. 214717, hex 0x346BD ) 
	
	The largest true binary value (all ones) is 11111111111111111 
		( dec. 131071, hex 0x1FFFF )

	While these are certainly possible, the largest absolutely useful value, that maximises all places in
	both binary, and hex, and thus is the true flag maximum is: 65535 (decimal). 
	This becomes 1111111111111111b, or 0XFFFF, which means that you may use each place to its full potential,
	at all times.

	Thus, the maximum useful flags are a width of 16-bit, and are represented below.
	
		Max Flag

		Binary               Hexadecimal    Decimal
		1111111111111111b    0XFFFF         65535

## COMPILER ERROR DEFINITIONS ##
################################
These errors are generated by the parser, during compilation.

Error codes are broken down by type:
P** Preprocessing errors.
S** Symbol table errors.
T** Type-checking errors.
G** Code Generation Errors
** Array Errors ---We need to change these to A**

Errors of each class are given unique numerical identifiers, ranging from 00 to 41, such as P01, or G33. 
The letter code will give you an indication of the type of error, and the full code will give you specific details.

In ZQuest v2.50.2 and later, the compiler will report name of the script that generated (where possible).
This applies only to errors caused by scripts, and not errors at a 'global' level, such as global functions.
Thus, if you are using 2.50.2, or later, an error without a script name is likely to be caused at global scope.

#####################
## Specific Errors ##
##  Preprocessing  ##
#####################

P00: Can't open or parse input file!

Your script file contains illegal characters, or is not plain ASCII Text.

Otherwise, it is possible that the compiler is unable to write to the disk, that the disk is out of space.

Last, your file may be bad, such as a file in the qrong encoding format (not ASCII text).

P01: Failure to parse imported file foo.

Generally means that you are trying to call a file via the import directive that does not exist; or that
you have a typo in the filename, or path.


P02: Recursion limit of x hit while preprocessing.

Caused by attempting to import a file recursively. For example:

If you declare: import "script.z" ... and ... the file 'script.z' has the line: ' import "script.z" ' inside it.

This error should no longer exist! Recursive imports should resolve as duplicate finction/variable/script declarations.

Error P03: You may only place import statements at file scope.

Import directives ( import "file.z" ) may only be declared at a global scope, not within
a function, statement, or script.

P35: There is already a constant with name 'foo' defined.
You attempted to define the same constant more than once.
The identifier (declared name) of all constants MUST be UNIQUE.

S04: Function 'foo' was already declared with that type signature.

You attempted to declare a function with the same parameters twice, int he same scope. 
This can occur when using different types, if the compiler cannot resolve a difference between the signatures.

To fix this, remove one function,or change its signature (the arguments inside the parens) so that each is unique or;
If you declare a functiona t a global scope, and the same at a local scope, remove one of the two.

Note that return type is NOT enough to distinguish otherwise identical function declarations and that 'int' and 'float'
types are the same type internally, so int/float is identical insofar as the signature is concerned.

If two function type signatures are identical except that one has a parameter of type float where the other has the 
same parameter of type int, you will have a conflict.

There are two additional subtle situations where you might get a conflict:

1. A function declared at file scope might conflict with a function that's implicitly added to file scope 
by the preprocessor because of an import statement.
2. A function might conflict with one already reserved by the ZScript standard library (std.zh). 

S05: Function parameter 'foo' cannot have void type.

You cannot set a parameter (argument of a function) as a void type. e.g.:
int foo(void var){ return var+1; }

This is illegal, and the param 'var' muct be changed to a legal type.

S06: Duplicate script with name 'foo' already exists.

Script names must be wholly unique. For example, if there's already an ffc script named 'my_script' you cannot 
declare an item script with the name 'my_script'.

S07: Variable 'foo' can't have type void.

Variables at any scope may not have a void type. Only functions may have this type.

S08: There is already a variable with name 'foo' defined in this scope.

Variable identifiers must be unique at any given scope. Thus, this is illegal:

ffc script my_ffc(){
    void run(int x){
        int v = 1;
        int w = 10;
        int x = 0.5;
        int y = 13;
        int z = v+w+x+y;
        Trace(z);
    }
}

As the variable 'x' is declared in the params of the run() function, it cannot be declared inside the function with 
the same identifier (name).
    

S09: Variable 'foo' is undeclared.

You attempted to reference a variable identifier (namme) that has not been declared.
Usually this is due to a typo:

int var;
if ( val > 0 ) Link->X += var;

Here, 'val' will return this error, as it was not declared.

A variable with the give name could not be found in the current or any enclosing scope. Keep in mind the following subtleties:
1. To access a different script's global variables, or to access a global variable from within a function delcared at file scope, 
you must use the dot operator: scriptname.varname.
2. To access the data members of the ffc or item associated with a script, you must use the this pointer: this->varname.
3. ZScript uses C++-style for loop scoping rules, so variables declared in the header part of the for loop cannot be 
accessed outside the loop:

Code:

for(int i=0; i<5;i++);
i = 2; //NOT legal

S10: Function 'foo' is undeclared.

You attempted to call a function that was not declared. This is usually due to either a typo in your code, or failing
to import a mandatory header. Check that you are importing 'std.zh' as well, as failing to do this will result in a slew
of this error type.

S11: Script 'foo' must implement void run().

Every script must implement run() function call. The signature may be empty, or contain arguments.
Zelda Classic uses all the code inside the run() function when executing the script, so a script without
this function would do nothing, and will return an error.

S12: Script 'foo's' run() must have return type void.

Is this error even implemented? The run() function is automatic, and never declared by type, unless the user tries to declare
a separate run(params) function with a different type.

S26: Pointer types (ffc, etc) cannot be declared as global variables.

/* It is illegal to declare a global variable (that is, a variable in script scope) or any type other than int, float, and bool. 
Why? Recall that global variables are permanent; they persist from frame to frame, screen to screen. 
Pointer types, on the other hand, reference ffcs or items that are transitory; they become stale after a single WAITFRAME, 
so it makes no sense to try to store them for the long term.
*/

This explanation may no longer be true, as pointers may no longer be dereferenced by Waitframe(), 
and global pointers may also be implemented in a future version.


S30: Script foo may have only one run method.

You may not call a run() function more than once per script.
Your run method may have any type signature, but because of this flexibility, the compiler cannot 
determine which run script it the "real" entry point of the script if multiple run methods are declared.

S32: Script foo is of illegal type.

The only legal script tokens are: global, ffc, and item. You cannot declare other types (such as itemdata script).

S38: Script-scope global variable declaration syntax is deprecated; put declarations at file scope instead.
You cannot declare a global variable in a global script, outside the run function.

Example:

global script active{
    int x;
    void run(){
        x = 16;
    }
}

This is ILLEGAL. The declaration of variable 'x' must either be at a global scope, or at the scope of the
run function. Do this, instead:

int x;
global script active{
    void run(){
        x = 16;
    }
}

This creates a global variable at the file scope. 

S39: Array 'foo' can't have type void.
Arrays may be types of int, float, bool, ffc, item, itemdata, npc, lweapon, or eweapon; but arrays
with a void type are illegal.

S40: Pointer types (ffc, etc) cannot be declared as global arrays.
As of 2.50.2, global array declarations may only have the following types:
int, float, bool
Any other type is illegal.

S41: There is already an array with name 'foo' defined in this scope.
As with variables, and functions, arrays must have unique identifiers within the same scope.

## LEXING ERRORS ##

L24: Too many global variables.

The assembly language to which ZScript is compiled has a built-in maximum of 256 global variables. ZScript can't do anything if you exceed this limit.

#####################
## Specific Errors ##
##  Type Checking  ##
#####################

T13: Script 'foo' has id that's not an integer.

/* I do not know what can cause this error, or if it ever occurs. */

T14: Script 'foo's' id must be between 0 and 255.

Occurs if you try to load more than 256 scripts of any given type at any given time.
/* The maximum number of concurrent scripts (of any given type?) is 256. */

T15: Script 'foo's' id is already in use.
You attempted to laod two scripts into the same slot. 
/* I do not know if this is EVER possible. */

T16: Cast from foo to bar.

The only "safe" implicit casts are from int to float and vice-versa (since they are the same type), 
and from int (or float) to bool (0 becomes false, anything else true). 
The results of any other kind of cast are unspecified.

/*
Is this error still in effect? Casting from npc to itemdata, or others, usually results in a different error code.
Further, Cannot cast from wtf to int, is a thing.
*/

Explicit casts are unimplemented and unnecessary.

T17: Cannot cast from foo to bar.

You attempted to typecast illegally, such as tyring to typecast from bool to float.

T18: Operand is void.
Occurs if you try to use a void type value in an operation.
/* I do not know if this is EVER possible. */

T19: Constant division by zero.

While constant-folding, the compiler has detected a division by zero

	Example: 
	const int MY_CONSTANT = 0;
	ffc script foo{
		void run(){
			int x = 6;
			Link->Jump = x / MY_CONSTANT;
		}
	}

Correct the value of your constant. Perhaps you meant to use a variable?

Note that only division by a CONSTANT zero can be detected at compile time. 
The following code, for instance, compiles with no errors but will generate script errors during execution. 

	Example:

	int x = 0;
	int y;
	y = 1/x;




T20: Truncation of constant x.

Constants can only be specified to four places of decimal precision, withing the legal range of values. 
Any extra digits are simply ignored by the compiler, which then issues this warning.

Any values greater than MAX_CONSTANT, or less then MIN_CONSTANT will result in this error.

## Applies to variables, but does not throw an error:
Both floats and ints can only be specified to four places of decimal precision. 
Any extra digits are simply ignored by the compiler, which then issues this warning.

Any values greater than MAX_VARIABLE, or less then MIN_VARIABLE will result in this error.

########

T21: Could not match type signature 'foo'.

When calling a function, you used the wrong number, or types, of parameters.
The compiler can determine no way of casting the parameters of a function call so that they 
match the type signature of a declared function. 

For instance, in the following snippet
Code:

int x = Sin(true);

since true cannot be cast to a float, this function call cannot be matched to the library function Sin, triggering this error.


T22: Two or more functions match type signature 'foo'.

If there is ambiguity as to which function declaration a function call should matched to, 
the compiler will attempt to determine the "best fit." 
These measures are however occasionally still not enough. Consider for instance the following snippet:
Code:

void foo(int x, bool y) {}
void foo(bool x, int y) {}
foo(1,1);

matching either of the two foo declarations requires one cast, so no match can be made. 
In contrast, the following code has no error:
Code:

void foo(int x, bool y) {}
void foo(bool x, bool y) {}
foo(1,1);

(The first foo function is matched.)

It is best to design functions so that noambiguity is possible, by addign extra params, to change the signature or by using 
different identifiers (function names) when using more params is not desirable.

T23: This function must return a value.

All return statements must be followed by an expression if the enclosing function returns a value. 
Note that the compiler does NOT attempt to verify that all executions paths of a function with non-void 
return type actually returns a value; if you fail to return a value, the return value is undefined. 
For instace, the following is a legal (though incorrect) ZScript program:

int foo() {}

/* I don't believe anythign ever returns this error.
I've seen functions with int/float/bool types, and no returns compile, without errors. 
Perhaps we should fix this, and issue a warning during compilation? */

T25: Constant bitshift by noninteger amount; truncating to nearest integer.

The bitshift operators (<< and >>) require that their second parameters be whole integers.

T27: Left of the arrow (->) operator must be a pointer type (ffc, etc).

It makes no sense to write "x->foo" if x is of type int. 
You may only use the dereference (->) operator on pointer types.

T28: That pointer type does not have a function 'foo'.

You tried to use the dereference operator (->) to call a function that does not exist for the pointer type being dereferenced. 
Check the list of member variables and functions and verify you have not mistyped the function you are trying to call.

This generally occurs when calling internal functions, using the incorrect class, or pointer, such as:

Game->Rectangle() instead of Screen->Rectangle()

The extra std.zh component 'shortcuts.zh' assists in preventing this error type.


T29: That pointer type does not have a variable 'foo'.

You tried to use the dereference operator (->) to call a member variable that does not exist for the pointer type being dereferenced. 
Check the list of member variables and verify you have not mistyped the variable you are trying to call.

This generally occurs when calling internal variables, using the incorrect class, or namespace, such as:

Link->D[] instead of Screen->D[]

/* The extra std.zh component 'shortcuts.zh' assists in preventing this error type.
Probaby not, as this requires silly amounts of functions to handle variables with identical identifiers.
C'est la vie. perhaps we'll do it, but I really am not fond of the idea. */

As above, but the member variable you tried to access does not exist.

Error T31: The index of 'foo' must be an integer.

/* This has been deprecated, so who cares? */


T36: Cannot change the value of constant variable 'foo'.

You cannot assign a CONSTANT to another value.

T37: Global variables can only be initialized to constants or globals declared in the same script.
You cannot (directly) simultaneously declare, and initialise a global value using the value of a variable at
the scope of another script, or function.

Example:
int x = script.a;
ffc script foo{
    int a = 6;
    void run(){
        for ( int q = 9; q < Rand(15); q++ ) a++;
    }
}

This is ILLEGAL. You cannot initialise the value of the global variable 'x' using the local value
of 'a' in the ffc script 'foo'.

/* I believe this is deprecated, as I do not believe that script level declarations remain legal */

T45 (old version, T38): Arrays can only be initialized to numerical values
You attempted to declare an array using a floating point value (e.g. 10.5), constant or equation, 
rather than a numeric literal.


    Consider that you want to declare an array with an explicit size of '40':
    These are ILLEGAL:
        int my_arr[26+14];
        const int CONSTANT = 30;
        int my_arr[CONSTANT];
        int my_arr[CONSTANT/2+20]
    
    YOu must declare an arrray with a numeric literal:
        int my_array[40];
        This is the only legal way to declare the size of an array as of 2.50.2.

G33: Break must lie inside of an enclosing for or while loop.

The 'break' keyword aborts the loop (in a for, while, or do statement) in which it is called.
You must be in a loop to break out of one, so calling 'break' outside of a loop is illegal.


G34: Continue must lie inside of an enclosing for or while loop.

The 'continue' keyword halts a loop, and repeats the loop from its head (in a for, while, or do statement) in which it is called.
You must be in a loop to continue one, so calling 'continue' outside of a loop is illegal.

As the above error, but with the continue keyword. Continue aborts the current iteration of the loop and skips to the next iteration.

Error A42 (old, Error O1): Array is too small. ( Converting to A42 in 2.50.3 )
You attempted to declare an array, with a set of values, where the number of values in the set
exceeds an explicit array size declaration:

int foo[4]={1,2,3,4,5};
The declared size is '4', but you tried to initialise it with five elements.

/* THis doesn't seem right, as this seems to be covered by Err 02. Check the source to see what causes this. */

Error O2: Array initializer larger than specified dimensions. ( Converting to A43 in 2.50.3)
You attempted to initialise an array, with a set of values, where the number of values in the set
exceeds an explicit array size declaration:

int foo[4]={1,2,3,4,5};
The declared size is '4', but you tried to initialise it with five elements.

Error O3: String array initializer larger than specified dimensions, space must be allocated for NULL terminator.
( Convering to A44 in 2.50.3 )
YOu attempted to seclare a QUOTEDSTRING of an explicit size, but you didn;t add space
for the NULL terminator; or you used more chars than you allocated:

int my_string[17]="This is a string.";
    THis allocates only enough indices for the chars, but not for the NULL terminator. 
    The array size here needs to be 18.
int my_string[12]="THis is a string.";
    You tried to initialise a QUOTEDSTRING that is longer than the array size.
    The minimum array size for this is '18'.
    
    It is generally best either to declare strings with an implicit size (set by the initialiser):
        int my_string[]="This is a string";
            This reads the nuber of chars, adds one to the count (for NULL), and sizes the array to 18.
    ...or...
    Declare the string with an arbitrarily large size:
        int my_string[256]="This is a string";
            This reserves 256 chars. Only 18 are used, and the rest of the indices
            are initialised as '0' (NULL). YOu may later populate the unused space, if desired.

You attempted to reference a game object that has a maximum legal range of 1 to 255. 
It is possible that you tried to read outside that range, or that the pointer that you were loading is not valid.
Check NumItems(), NumLWeapons(), NumEWeapons(0, and NumNPCs() before referencing them; and verify that the object ->IsValid()
Check for loops that may attempt ro reference items outside of the range that actually exist.
Look for any for loops that access these objects, that start, or end at zero.

The best way to ensure this does not occur, is to make a for loop as follows:

	for ( int q = 1; q < Screen->NumLWeapons; q++ )

			//or//

	for ( int q = Screen->NumLWeapons(); q > 0; q-- ) 

...replacing NumLWeapons() withthe appropriate type that you are attempting to load.

You may be attempting to refrence a pointer that has fallen out of scope.
You may be attempting to reference a pointer that is no longer valid, or has been removed.
Check ( pinter->IsValid() ) by itself, to ensure this does not occur:

		if ( pointer->IsValid ) {
			if ( pointer->ID == LW_FIRE ) //Do things.
		}
	
This helps to prevent loading invalid pointers.
